# Caller ID Formats

You can edit Caller ID format settings in the **Voice > Inbound Trunks** section. Each SIP trunk you create can have its
own Caller ID settings. The available Caller ID formats are:

> | Format | Description | Example |
> | --- | --- | --- |
> | **RAW** | Sends the Caller ID exactly as it is received from the originating side. | Caller ID is sent without modification. |
> | **E.164** | Sends the Caller ID in the format +<Country Code><Area Code><Number>. | +1 212 5551234 (United States, Country Code: 1, Area Code: 212, Number: 5551234) |
> | **LOCAL** | Sends the Caller ID in the local format <Area Code><Number>. | 212 5551234 (Area Code: 212, Number: 5551234) |

To further modify the Caller ID, use the **CLI Prefix** input field (Fig 1.). This setting allows you to add a prefix to
the Caller ID. For example, if you specify the + symbol, it will be added at the beginning of every received Caller ID.

Note

DIDWW ensures the accurate transfer of Caller ID (CLI) for all local calls. However, the accurate transfer of
international Caller IDs may not always be guaranteed due to factors beyond DIDWW's control, such as third-party
provider limitations.
